The ASMi-52 SHDSL modem uses TC PAM-16 line coding SHDSL technology to extend the range of digital interfaces. The ASMi-52 SHDSL modem offers longer distances and variable data rates up to 2.3 Mbps over 2-wire and 4.6 Mbps over 4-wire.

Built-in multiplexer

The ASMi-52 SHDSL modem has a built-in multiplexer capability with two user ports. It can transmit combinations of V.35/X.21/RS-530 data, 10/100BaseT LAN and E1 traffic together over a single SHDSL link at a maximum data rate of 2.3 Mbps.

Ethernet extension

The ASMi-52 SHDSL modem extends the range of 2 Mbps data more than 4 km over 2-wire or 4-wire, reaching a maximum of 10 km (6.2 miles) for 64 kbps data. It supports E1 and T1, V.35, X.21 and RS-530 data, Ethernet bridge, and IP router user interface options.

For LAN-to-LAN connectivity, the modem supports a built-in 10/100BaseT Ethernet port with VLAN support.

The ASMi-52 is compatible with 2/4-wire repeaters, such as RAD’s S-RPT, for supporting even longer-range applications.

It also works opposite RAD’s LRS-24 modem rack, DXC, and Megaplex SHDSL modules. Monitoring, control and diagnostics of local and remote units are available via a supervisory port. Standards compliance enables the ASMi-52 modem to work opposite third-party TDM equipment that supports the SHDSL standard.

The ASMi-52 SHDSL modem is available as a standalone unit or as a card for the LRS-24 19-inch rack with central SNMP management.

It is also available in a rugged metal enclosure designed for easy installation on cabinet rail mounts that meet the EN 50121-4 industry standard.

The management connection to the standalone unit is via:

• V.24/RS-232 port using SLIP protocol
  
• Out-of-band Ethernet port
  
• Dedicated timeslot using E1/T1 port
